That might be cutting it close for coral. You may be able to keep really low light coral in there but it would not be optimal conditions. I would say at least a 2 bulb fixture if you want to keep coral.

I understand completely; I'm always reefing with a budget in mind. How wide is you bowfront? I've seen some decent lights (dual T5 HO) for under $100. But they may still not be enough wattage for your situation.

If you were to go with the Current USA Novas, got to petmountain.com; they're almost $20 cheaper there. Your tank is narrow (about the size of a rectangular 10G) and high. If you wanted to keep almost any kind of corals, you're probably going to have to go with metal halides and those aren't cheap.
